Canon G9 X vs SX70
The Canon PowerShot G9 X and the Canon PowerShot SX70 HS are two digital cameras that were officially introduced, respectively, in October 2015 and September 2018. Both the G9X and the SX70 are fixed lens compact cameras that are based on an one-inch (G9X) and a 1/2.3-inch (SX70) sensor. The G9X has a resolution of 20 megapixels, whereas the SX70 provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Canon PowerShot SX70 HS? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Canon G9 X and the Canon SX70 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The G9X can be obtained in two different colors (black, silver), while the SX70 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX70 is considerably larger (103 percent) than the Canon G9 X. Moreover, the SX70 is substantially heavier (191 percent) than the G9X. In this context, it is worth noting that neither the G9X nor the SX70 are weather-sealed.
Concerning battery life, the G9X gets 220 shots out of its NB-13L battery, while the SX70 can take 325 images on a single charge of its LP-E12 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G9X was somewhat cheaper (by 4 percent) than the SX70 at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X features an one-inch sensor and the Canon SX70 a 1/2.3-inch sensor. The sensor area in the SX70 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G9X has a native 3:2 aspect ratio, while the one in the SX70 offers a 4:3 aspect.
Technology-wise, the SX70 uses a more advanced image processing engine (DIGIC 8) than the G9X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX70 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the G9X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 2.41μm for the G9X). However, it should be noted that the SX70 is much more recent (by 2 years and 11 months) than the G9X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX70 HS are ISO 100 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the SX70 provides a better video resolution than the G9X. It can shoot movie footage at 4K/30p, while the G9X is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX70 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G9 X and Canon SX70 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X has a touchscreen, while the SX70 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The SX70 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the G9X does not have a selfie-screen.
The Canon G9 X has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Both the G9X and the SX70 have zoom lenses built in. The G9X has a 28-84mm f/2.0-4.9 optic and the SX70 offers a 21-1365mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the SX70 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X. The G9X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G9X and the SX70 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G9 X and Canon PowerShot SX70 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX70 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G9X does not feature such a mic input.
The SX70 is a recent model that features in the current product line-up of Canon. In contrast, the G9X has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon G9 X better than the Canon SX70 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon PowerShot G9 X:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the count of relative strengths (bullet points above) is taken as a measure, the G9X comes out slightly ahead of the SX70 (14 : 13 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G9X or the SX70. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
